Answer:
( z - 5 ) ( z - 5 )
Step-by-step explanation:
z² − 10z + 25
= z² − 5z - 5z + 25
= z ( z - 5 ) - 5 ( z - 5 )
= ( z - 5 ) ( z - 5 )
Answer:
This is not possible.
Step-by-step explanation:
The given series is : 2 , 6, 10, 14, 18, 22, 26, 30, 34, 38, 42, 46, 50, 54, 58
Now, adding any three numbers to get 60, is not possible.
The numbers are in the form where n is a positive integer.
Summing together three such numbers you get
(N = n1 + n2 + n3, ...)
We want to get
=>
=>
Hence, it is not possible.
